138255 - Miller .030-.035 Teflon Liner for Aluminum Wire - 14ft

Smooth Aluminum Welding Starts Here

If you have ever tried to weld aluminum with a standard steel liner, you know the headache: the wire binds, the feed stutters, and eventually, you end up with a bird's nest of tangled wire at your feeder. The Miller 138255 Teflon Liner is the solution to these common shop frustrations. Specifically designed for running .030" to .035" aluminum wire, this liner replaces the abrasive steel coil in your MIG gun with a smooth, slippery Teflon tube that lets soft wire slide through without resistance.

Aluminum is tricky. It's soft, it bends easily, and it hates friction. This 14-foot liner reduces that friction to almost zero. This means your drive rolls don't have to work as hard, and the wire stays straight and true all the way to the puddle. The result? A steady, humming arc and beautiful stacked-dime welds, rather than sputtering and burn-backs. This liner is a genuine Miller part, meaning it is built to the exact dimensions required for your Miller MIG gun, ensuring no gas leaks or loose fittings.

Maintenance is key to good welding. Over time, even Teflon liners can wear out or get kinked. Swapping in a fresh 138255 liner is one of the cheapest and most effective ways to tune up your aluminum welding setup. It is perfect for anyone working on aluminum boats, trailers, or custom fabrication projects. Don't let feed issues ruin your workpiece—upgrade to the proper liner and feel the difference in your gun.

Why Choose Teflon?

• Zero Shaving: Doesn't scrape soft wire like steel liners do.
• Consistent Feed: Slippery surface prevents binding and stuttering.
• Cleaner Welds: Prevents metal debris from entering the weld pool.
